The room is 15yd × 10yd
so 15×10=150
the room is 150 square ft
Answer:
x = 14
Step-by-step explanation:
Let's solve your equation step-by-step.
6(x − 5) = 54
Step 1: Simplify both sides of the equation.
6(x − 5) = 54
(6)(x) + (6)(−5) = 54(Distribute)
6x + − 30 = 54
6x − 30 = 54
Step 2: Add 30 to both sides.
6x − 30 + 30 = 54 + 30
6x = 84
Step 3: Divide both sides by 6.
6x/6 = 84/6
x = 14
Answer:
B, C, E are true
Step-by-step explanation:
A = l*w
The original rectangle is 6 by 4 with A = 24
The 1st enlargement = 6*3 by 4*3
18 by 12 with A = 216
The second enlargement is 18*3 by 12*3
54 by36 with A =1944
A.The area of the first enlargement is 72 square inches.
False it is 216
B.The area of the second enlargement is 1,944 square inches.
True
C.The area of the second enlargement is (3 squared) squared times the original area.
216/24 =9 True
D.The area of the second enlargement is 3 times the area of the first enlargement.
1944/24 = 9 False
E.The ratio of the area of the first enlargement to the area of the original equals the square of the scale factor.
The scale factor is 3 3^2 =9 216/24 =9
True
